Brand: Hitachi

The Hitachi HA-4700 is a high-performance supercomputer that was introduced in 1996. It was designed for applications in weather forecasting, aerospace engineering, and materials science, among others. Some of its key features include:1. Processor: The HA-4700 uses Hitachi's SH3 RISC processors, which were capable of operating at a clock speed of 250 MHz. It could support up to 512 processors in a single system, making it one of the most scalable supercomputers of its time.2. Memory: The HA-4700 could accommodate up to 48 GB of memory, which was a significant improvement over its predecessor, the HA-4400. This allowed it to handle larger data sets and more complex applications.3. Input/Output: The HA-4700 featured a high-speed parallel I/O subsystem that could deliver up to 19 GB/s of data transfer rates. It also provided support for various storage devices such as Fibre Channel and SCSI hard disks, as well as magnetic and optical tape units.4. Operating system: The HA-4700 ran on Hitachi's proprietary HI-UX operating system, which was based on UNIX System V.5. Applications: The HA-4700 was particularly popular in scientific and engineering applications due to its high performance and scalability. Some of the major applications it supported included weather forecasting models, computational fluid dynamics simulations, and finite element analysis in materials science.The HA-4700 established Hitachi as a major player in the supercomputer market, and it helped pave the way for the company's continued success in this field. Today, Hitachi's supercomputers are used in a wide range of industries, from finance and oil and gas to biotech and climate research. The HA-4700 may be a relic of the past, but its impact on the evolution of supercomputing technology cannot be overstated.
